Lobendahn, a fourth-year junior, is starting at left tackle for the first time since his freshman season in 2014, replacing Chad Wheeler. Brown, a fourth-year junior, is the full-time starter at left guard for the first time, replacing Damien Mama.

Helton, after assessing Brown's block, called it "by far his best game since being a Trojan."

For Lobendahn, he has returned from two consecutive season-ending knee injuries.

"We've had great communication so far up front," right guard Viane Talamaivao said.
